At the same time however, around a hectare a year of green land is being gained due to regeneration of old industrial areas.

The independent study, produced by scientists at the Centre for Ecology & Hydrology (CEH), looked at the two elements of urbanisation:

Urban expansion—The development of new housing or industrial estates being built on farmland or recreational spaces. These developments are subject to rigorous planning policies to ensure they do not increase flood risk.

The CEH scientists developed a method to map urbanisation using aerial photography of Edinburgh from 1990, 2005 and 2015—resulting in the first high-resolution, city-wide estimates in Scotland. This method could be applied to other cities and towns across Scotland to map urbanisation and assess potential impacts.

Dr. Clare Rowland, an earth observation scientist at CEH who led the research, said: "Our study shows that, over the last 25 years, Edinburgh lost an average of 11.3 hectares (ha) of green land each year to urban creep and urban expansion. That's equivalent to about 15 football pitches annually.

"People might assume that most of this loss is from urban expansion, through the...
